Towards the Creation of Metal Hydrogen.Hydrogen is one of the most common element on earth, and are usually present in the form of gas, but at very high pressure hydrogen can act as superconductors. Scientists from the Carnegie Institution in Washington DC United States now has succeeded in creating a hydrogen-based compounds that may help other researchers to study the superconducting properties of kelogaman and hydrogen. The results of their research has been published in "Physical Review Letters and Higighted on August 3 Physiscs APS online journal.

Hydrogen is the simplest element Paing, consisting of one proton and one neutron. This hidroge caused very light, then according to quantum theory of hydrogen would have a certain amount of energy even though he cooled at very low temperatures. This is what causes why hydrogen freezes at a temperature of 14 degrees above absolute zero temperature.

Yeah many scientists predict that we may be able to make the metal hydrogen, but they also predict that the ogam hydrogen to create the necessary pressure is atmospheric pressure of 4 million, where the pressure exceeds the pressure in the center of the earth. By forming hydrogen compounds by using other elements such as Si it is possible to make a more solid hydrogen can be moderate to metal at a pressure which can be reached experimentally. In fact, SiH4 into the metal is at one-tenth the pressure needed to make metallic hydrogen from pure hydrogen, and are superconductors at 1 million atmospheres of pressure.

In their paper, Timothy Strobel, Maddury Somayazulu, and Russell Hemley present extensive high-pressure experiments on a mixture of SiH4 and H2. At pressures of only ~ 7.5 GPa, they discovered a new compound - SiH4 (H2) 2 - in which the hydrogen bonds are unusually weak and which may become a metal at higher pressures.

The ultimate goal of such studies is to generate the conditions under which hydrogen becomes metallic effectively, and hopefully superconducting, at lower pressures than those required for pure solid hydrogen.

In their journals, Timothy Strobel, Maddury Somayazulu, and Russell Hemley has been experimenting with using high pressure in the mixture SiH2 and H2. At pressure 7.5 GPa only, they found a new compound SiH4 (H2) 2 where the hydrogen bonds in these compounds are not normally the weak bonds and a metal at high pressure.

The purpose of this research is to determine the conditions in which hydrogen is effectively a metal and superconductor, at a lower pressure than the pressure of pure solid hydrogen.
